ANTISLIPPING DEVICE.

Specification of Letters Patent.

Patented Apr. 30, 1912.

Application filed August 'l, 1911. Serial No. 642,329.

To all whom it may concern:

Be it known that I, WILLIAM FINDLAY, a. citizen of the United'States ofAmerica, and a resident of the city of New York, Long Island City,borough of Queens, in the county of Queens and State of New York, haveinvented a new and Improved Antislipping Device, of which the followingis a full, clear, and exact description.

My invention relates to anti-slip ing devices -to be worn upon the sole0 a shoe and provided with means for their easy removal and replacement,and also for their reversal so that when worn from one side they may beturned over so as to expose the fresh antislippin surface to the ground.

Reference is to he had to the accompanying drawin forming a part of thisspecification, in w ich like characters of reference indicatecorresponding parts in all the views, and in which-- Figure 1 is aperspective view showing a shoe provided with my improved anti-slippingdevice; Fig. 2 is an inverted plan or bottom view of the anti-slippingdevice; Fig. 3 is a front view showing the anti-slipping device in crosssection, the shoe appearin in elevation; and Fig. 4 is a section throughthe anti-slipping device and is taken on a plane crossing the generaldirection of the length of the strap.

A shoe 5 is provided with a sole 6 and is of the usual or any desiredconstruction. I provide a strap 7 having a portion 8 bent backwardly soas to form a loop 9, this loop carrying a buckle 10 throu h which thefree end of the strap may be s iipped, the strap being secured in amanner well known in this art. I also provide two plates 11 of sheetmaterial, and in this instance circular in form. The plates 11 are, bythe simple operation of punching or stamping, provided with rough teeth12 which are merely integral portions of the plates 11 turned outwardly.

Two plates 11 are secured together by aid of rivets 13. These rivets arespaced far enough apart to allow the plates a little room in which tobend in order that the strap 7 may be threaded between them. The plates11 are placed back to back; that is, the teeth of one plate extending ina direction opposite to the teeth of the other plate. The two plates,when thus secured together, are reversible relatively to the strap; thatis to say, the pair of plates, as a unit, may

be slip ed ofi' the strap, turned over, and placed back on the strap inorder that either of the two roughened surfaces maybe outside of thestrap when the strap occupies the position indicated in Fig. 1. Afterthe plates 11 have been secured together by the rivets 13 the same arebent slightly apart for accommodating strap 7.

The operation of my device is as follows: The unitary member, consistingof the two plates, is fitted upon the strap as shown, and the strap isbuckled upon the shoe as indicated in Fig. 1. The shoe now being lacedupon the foot, whenever the user wal (s, the

lowermost group of teeth is forced down flat upon the ground or upon anyother surface on which the user is supported. The presence of the teeth12 and .their roughness prevents the shoe from slipping.

My device is of peculiar value to enable people to walk upon the ice andsnow with out the danger of falling.

I do not limit myself to the mechanism shown, as numerous variations maybe made therein without departing from the spirit of my invention.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is za 1. As an article of manufacture, anantislip ing device comprising a pair of plates of s eet metal eachprovided with teeth,said plates being so located relatively to eachother that said teeth carried by one plate extend in a directionopposite to that of the teeth carried by the other plate, and a strapextending between said plates for supporting the same upon a wearersfoot.

2. A device of the character described, comprising a pair of plates ofsheet metal; each plate being provided with teeth formed integrally withit, the teeth of one plate extending in a direction opposite to that ofthe teeth of the other plate, a. plurality of rivets extending throughboth plates for holding them together, said rivets being spaced apart,and a strap extending between said' plates for supporting the same upona wearers foot.

3. As an article of manufacture. a pair of plates of sheet metal, eachplate being provided with teeth integral with it, the teeth of one plateextending in a direction opposite to that of the teeth of the otherplate, and a plurality of fastening members con necting said platestogether, said plates being bent slightly apart so as to permit thepassage of a strap between said plates.

4:. A device of the character described, comprising a reversibleanti-slippi"ng'mem-; her, and a retaining strap adapted to secure saidanti-slipping member in position with either face uppermost.

5. A device of the character described, comprising a pair of duplicateanti-friction plates, a projection formed on each plate, means forsecuring said plates together so that said projections will extend inopposite directions, and a retaining strap adapted to secure said platesin position Witheither plate uppermost.

hold either side of sald -comprising anti slipping means formed withopposite sides of substantially identical c0n- "SEIUCti'OIr, and aretaining strap extending through said anti-slipping means adapted toanti-slipping means uppermost.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
